22 Bishopsgate is one of 13 major build projects expected to change London’s skyline by 2026.

Designed by PLP Architecture, 22 or ‘Twentytwo’ Bishopsgate stands 278 metres tall as the City of London’s tallest tower within the financial districts new ‘City Cluster‘. The tower provides over 1.2 million sq ft of office space and can accommodate up to four tenants on each of the 62 floors.

Over 17,000 tonnes of superstructure structural steelwork and metal decking was designed and fabricated for construction by Severfield, who approached Farrat during fabrication to supply a suitable solution to mitigate against thermal bridging between connections.

Superelevations, axial shortening and complex geometrical dilemmas presented challenges on this project, so Farrat worked closely with Severfield to manufacture a package of structural thermal breaks in various sizes, shapes and thicknesses to fit seamlessly into design details and meet specification.

Farrat’s load-bearing structural thermal breakmaterial with the highest levels of compressive strength and thermal insulation, was used between steel-to-steel connections to prevent thermal transfer from the exterior of the structure into the internal structure via the steel framework.

Farrat thermal break plates were also used in steel-to-concrete applications to greatly reduce heat loss into the concrete slab, providing better insulation for the structure overall.

‘Twentytwo’ Bishopsgate is due for completion later this year.

Farrat’s BBA certificated structural thermal break materials provide building design professionals with a robust solution to minimise energy loss. Suitable to mitigate against planar, linear and point load thermal bridging, Farrat thermal breaks can be used anywhere a penetration or transition exists in a building envelope to help achieve building performance standards. Performance characteristics include low thermal conductivity, high compressive strength and very limited creep under load.
